Related to the discussion about planetary periods in relation to the QBO periodicity and your comment in theENSO thread at 202.
I now finally looked at the cycles. You claimed that 2.34 is
an important moon period. How does this come about? Like if I calculate 365.242 *2.34 and divide this by the lunar month 27.321 I get 31.284. Not that a good match. Or is the 2.34 rounded?
By the way did you look also at other cycles in the terrestial planet system? Like Jupiter seems to have quite an impact on the sun (on a first glance it looks this cycle is related to the solar activity) so other planets could also play a role.
